Abstract

The invention discloses a display apparatus. The display apparatus includes a display panel, wherein the display panel includes a pixel array; the pixel array includes a first integer pixel row, a second integer pixel row, a first integer of scanning lines, a second integer of data lines, a second integer adjusting device row, a scanning drive circuit, and a data drive circuit, wherein the first integer pixel row includes a second integer of pixels; the second integer pixel row includes a first integer of pixels; the second integer adjusting device row includes a third integer of adjusting devices; the third integer of adjusting devices are arranged between every two adjacent pixels in the pixel array; the scanning drive circuit includes a first integer of scanning drivers; and each adjusting device is used for adjusting the time delay value when a data signal generated from the data drive circuit is input in the pixel so that the first time of duration that a switch of the pixel is in the on state is corresponding to the second time of duration that the data signal is input in the pixel through the switch. The display apparatus can avoid occurrence of the situation that a horizontal block with nonuniform upper and lower brightness so as to improve the display quality.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display device. 【Background technique】 [0002] Traditional VA (Vertical Alignment, Vertical Alignment) display mode displays H-blocks (horizontal blocks with uneven brightness) when displaying low-gray-scale images, such as figure 1 As shown, this phenomenon will reduce the display quality of the display device. [0003] The reasons for the above H-block phenomenon are generally: [0004] The wires (WOA, Wire On Array) between the scan drivers corresponding to different scan lines have a certain resistance value, and the resistance value makes the different scan lines transmit scan signals to the pixels in the same column. A certain time delay phenomenon occurs in the pixel (pixel A and pixel B), which will cause the scan signal transmitted by the scan line and the data signal transmitted by the data line to charge the pixel insufficiently or incorrectly due to th...
